Engine Smokes When Hot at Idle

[cbeaus]

I have a 1992 Dyna custom when the engine gets up to normal operating temperature the motor will smoke at idle. It does not smoke when cold and I have not been able to detect it smoking when I am moving only at idle. The smoke lookes to be more gray than blue. I have an oil cooler on the bike. Anyone have any ideas as to what the problem might be?

Being a 92 and you didn't mention the miles on it, I would do a compression test and if that doesn't give you answers, try a leak down test. You'll find them both in the self help forum .
Chances are you have worn rings or valve seals of maybe even an damaged oil ring in one cylinder.

Thanks I will do the compression test this weekend. By the way the bike just turned 31,000 miles.
